Scalar implicatures in complex sentences

This article develops a Gricean account for the computation of scalar implicatures in cases where one scalar term is in the scope of another. It shows that a cross-product of two quantitative scales yields the appropriate scale for many such cases. One exception is cases involving disjunction. For these, I propose an analysis that makes use of a novel, partially ordered quantitative scale for disjunction and capitalizes on the idea that implicatures may have different epistemic status.
